i own a 2005 audi A4 B7 2.0TDI. 100k The cars been runinng fine up until the last few months were ive had one problem after
the other and im beginning to lose hope with it the car has always been serviced at audi. on my last service audi said that there was vibration on idle and they suspect it was the flywheel so got it changed. problem still there. spent a load of cash for nothing. i know ppl say that there is some vibration in the engine but this amount is not normal. also the car shudders in low revs in most gears, but only does it sometimes and not all the times. feels like the car is misfiring. alot of ppl say the egr may cause this but not had a chance to look at this. had the car VAG and no codes.
3rd problem, black smoke when hard accelerating. not the normal diesel smoke but heavy black smoke.
4th problem, heaters have stopped blowing warm air out. the car temp rises but the air is luke warm.
5th problem, your all thinking i should have scrapped the piece of crap by now.lol. anyways the car makes a knocking sound from the engine when the heaters are off but when they on theres no sound. i suspect this may be the compressor or sumat. but dont realy know. the car doesnt feel like it was when I 1st got it. I need to get the car on a VAG machine and see if there is any fault codes for the above and will post as soon as ive got it done. any help would be realy helpful. i dont want to take if to stealers. they ripped me off already and if anyone has experianced these please tell me.
